Role Number : 200626459-3956

Summary

At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? As a member of our Wireless Silicon Design group, you will have outstanding and exciting opportunity to build our future products that will delight and encourage millions of Apple’s customers every single day!

Would you like to join Apple’s growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development, taking care of challenges from the complex usages, more demanding performances and reliabilities to enable emerging wireless applications and products. Our goals are to come up with innovative architectures and protocols, integrate systems and algorithms with employing the advanced technologies to introduce our innovative products, providing evolutions to our lives.

Description

In this technical role, you will be at the center of a silicon design group, with a critical impact on radio architecture, radio system performance, system integration and physical layer algorithms designs for innovative wireless communication systems. You will develop system model of RF / analog design, radio chain modeling, integrated radio interaction models, dynamic behavior models and assess associate impairments. You will evaluate radio performance on various application scenario, as well as working on architecting various calibration and correction methods for radio impairments.

The role requires collaboration with HW digital designers and architects, products, Radio, analog designers, and SW engineers, to define and specify the wireless systems. You will get to work with digital designers to realize different physical and / or radio compensation algorithms, and with firmware designers to realize different physical / radio compensation algorithms with high efficiency software implementation. And to bring up, test, characterize and optimize real silicon in lab to the production qualities.

Minimum Qualifications

BS with 10 years of relevant experience required.

Understanding of RF and analog components / modules composited of wireless communication systems, the possible impairments from those components, and the corresponding calibration and impairment reduction methods / algorithms is essential

Consistent track record of RF calibration algorithm for RF impairments

Experience with MATLAB, Python and / or C / C++ for algorithm development, modeling, and simulation.

Hands-on experience on lab testing & characterization, such as spectrum analyzer, signal generator, signal analyzer, power meter.

Preferred Qualifications

MSEE / PhD with relevant experience

Understanding of communication theory, information theory, & signal processing related algorithms design

Analytical capability to develop the best-in-class solution in terms of performance, power and area for the meaningful issues of physical layer design

Knowledge in existing wireless communication protocols : Cellular technologies (5G-NR / LTE / WCDMA / GSM), WiFi (802.11a / b / g / n / ac / ax / be and ad / ay) or Bluetooth / BLE
